Scenario

When a storage pool enters a degraded state in a high-availability (HA) cluster, services may continue to run. However, the cluster loses some fault tolerance. We recommend repairing the degraded storage pool as soon as possible to maintain data protection and avoid potential data loss.

Solution

Tip

Ensure that your important data is backed up before performing any storage actions.

Identify the faulty disk in your degraded storage pool.
1. Log in to the active node as an administrator.
2. Go to Storage Manager > Storage Space.
3. Locate the storage pool with a "Degraded" status.
4. Under Action, click ⋮ > Manage.
  The storage pool management page appears.
5. Go to the RAID tab.
6. Identify the faulty disk.
Replace the faulty disk.
1. Physically remove the faulty disk.
2. Replace it with a healthy disk of the same or greater capacity.
3. Ensure the new disk is detected and appears in the disk list.
Wait for the storage pool to rebuild.
1. Go back to Storage Manager > Storage Space.
2. After replacing the faulty disk, the pool status should change to "Rebuilding".
  During the rebuild process, the system will automatically synchronize data between the cluster nodes.
  Important
  Do not power off or remove any other disks during the rebuild process.
3. Once the rebuild process is complete, the pool status changes to "Ready".
Check HA functionality.
Note
We recommend performing a switchover to verify the active and passive nodes can switch roles normally and that HA functionality has been fully restored.
1. Go to High Availability Manager > Cluster.
2. Click Manage, and then click Switch Over.
  A confirmation window appears.
3. Click OK.
  High Availability Manager performs the switchover.
4. After the switchover is complete, ensure the nodes have switched roles and the cluster status is "Good".

Scenario

Når en Lager-pulje går ind i en degraderet tilstand i en højtilgængelighed (HA) Klynge, kan tjenester fortsætte med at køre. Dog mister Klynge noget fejltolerance. Vi anbefaler at reparere den degraderede Lager-pulje så hurtigt som muligt for at opretholde databeskyttelse og undgå potentielt datatab.

Løsning

Tip

Sørg for, at dine vigtige data er sikkerhedskopieret, før du udfører nogen Lager-handlinger.

Identificer den defekte disk i din degraderede Lager-pulje.
1. Log ind på den aktive node som en administrator.
2. Gå til Lager Manager > Lager Space.
3. Find Lager-puljen med status "Degraderet".
4. Under Handling, klik ⋮ > Administrer.
  Siden til administration af Lager-puljen vises.
5. Gå til RAID fanen.
6. Identificer den defekte disk.
Udskift den defekte disk.
1. Fjern fysisk den defekte disk.
2. Udskift den med en sund disk af samme eller større kapacitet.
3. Sørg for, at den nye disk bliver registreret og vises i disklisten.
Vent på, at Lager-puljen genopbygges.
1. Gå tilbage til Lager Manager > Lager Space.
2. Efter udskiftning af den defekte disk bør puljestatus ændres til "Genopbygning".
  Under genopbygningsprocessen vil systemet automatisk synkronisere data mellem Klynge-noderne.
  Vigtigt
  Sluk ikke eller fjern andre diske under genopbygningsprocessen.
3. Når genopbygningsprocessen er fuldført, ændres puljestatus til "Klar".
Kontroller HA-funktionalitet.
Bemærk
Vi anbefaler at udføre en rolleombytning for at verificere, at de aktive og passive noder kan skifte roller normalt, og at HA-funktionaliteten er fuldt genoprettet.
1. Gå til High Availability Manager > Klynge.
2. Klik Administrer, og klik derefter Skift rolle.
  Et bekræftelsesvindue vises.
3. Klik OK.
  High Availability Manager udfører rolleombytningen.
4. Efter rolleombytningen er fuldført, skal du sikre dig, at noderne har skiftet roller, og at Klynge-status er "God".
